A first trip abroad goes wrong in predictable places: an expiring passport, a fare bought before the dates were sure, a phone bill, a card declined in a foreign ATM. Here is the whole sequence, in order, so none of those happen to you.
Three months out: documents
- Passport. A first adult passport book costs $165 and is valid ten years (United States passport). Apply now; processing takes weeks and longer in spring. If you already have one, check that it is valid six months beyond your return, which many countries and airlines require.
- Entry rules. Most of Europe, Japan, the UK, Mexico and the Caribbean admit US tourists without a visa, but several countries need an e-visa or electronic authorization in advance, and the Schengen Area limits visa-free stays to 90 days in any 180 (Wikivoyage: Schengen). Check your destination on the State Department's country page. Our passport and visa guide covers the details.
- Enrol in STEP, the State Department's traveller enrolment programme, so the nearest embassy can contact you in an emergency.
Two to four months out: the flight
- Decide dates with a little flexibility; midweek departures are usually cheaper.
- Check the current fare on the route page, for example JFK to London, JFK to Paris, LAX to Tokyo or Miami to Cancún.
- Set a price alert at a price you would be happy to pay and let it watch. See when to book flights for the typical windows.
- When you book, book directly with the airline if you can. Tickets bought at least seven days out can be cancelled within 24 hours for a full refund (Thrifty Traveler), which is your safety net for a typo in a name or a date.
- Enter your name exactly as it appears in your passport.
Six weeks out: money, phone, health
- Cards. Take at least two cards with no foreign transaction fee, from different networks if possible, and tell the issuers your dates if they still ask. Use ATMs attached to banks for cash and always choose to be charged in local currency, not dollars, when a machine or terminal offers the choice.
- Phone. Choose between your carrier's international day pass, an eSIM bought before you leave, or a local SIM on arrival. Download offline maps and your airline's app.
- Health. Check the CDC's destination page for recommended vaccines and build a small travel health kit: prescriptions in original containers with copies, basic first aid, insect repellent with DEET or picaridin, and sunscreen (CDC Pack Smart).
- Insurance. At minimum, emergency medical and evacuation cover; see our travel insurance guide.
Two weeks out: lodging and logistics
- Book the first night's lodging even if the rest is flexible; immigration officers sometimes ask, and you do not want to hunt for a room jet-lagged.
- Work out how you will get from the airport to your bed: train, official taxi rank, pre-booked transfer. Write it down.
- Save offline copies of your passport, tickets, insurance and reservations, and email them to yourself.
- Learn a dozen words of the language: hello, please, thank you, excuse me, how much, where is, the numbers.
The week before: packing
- Aim for carry-on only if your fare allows it; see the carry-on packing guide.
- Liquids in containers of 3.4 oz / 100 ml or less in one quart bag (TSA).
- A universal plug adapter, a power bank, and one layer more than you think you need.
- Check in online 24 hours before departure and confirm any visa or authorization is approved.
On arrival
- Immigration, then baggage (if any), then customs. Have your return ticket and first-night address ready.
- Get cash from a bank ATM in the arrivals hall, not a currency-exchange counter.
- Take the transport you planned; ignore touts.
- Adjust to local time immediately: daylight, a walk, and a normal bedtime beat a nap.
Common first-timer mistakes
- Booking the flight before checking passport validity.
- Buying non-refundable hotels before the flight is ticketed.
- Exchanging cash at the airport counter.
- Over-planning every day; leave room.
- Not checking whether your destination needs an e-visa until the week before.
FAQ
How far in advance should I plan my first international trip? Start three months out for the passport, watch fares from two to four months out, and book lodging once the flight is ticketed.
Do I need a visa for my first trip to Europe? Not for tourist stays up to 90 days in the Schengen Area; a pre-travel authorization is planned, so check the official EU site before you go.
Should I exchange money before I leave? A small amount is fine; a bank ATM at the destination usually gives a better rate than a US exchange counter.
